求助各位翻译大师，很急，各路大虾快来帮忙翻译

If your USB-TC is damaged, notify Measurement Computing Corporation immediately by phone, fax, or e-mail. For international customers, contact your local distributor where you purchased the USB-TC.
To connect the USB-TC to your system, turn your computer on, and connect the USB cable to a USB port on your computer or to an external USB hub that is connected to your computer. The USB cable provides power and communication to the USB-TC.
When you connect the USB-TC for the first time, a Found New Hardware popup balloon (Windows XP) or dialog (other Windows versions) opens as the USB-TC is detected.
When this balloon or dialog closes, the installation is complete. The USB LED should flash and then remain lit. This indicates that communication is established between the USB-TC and your computer.
Caution! Do not disconnect any device from the USB bus while the computer is communicating with the USB-TC, or you may lose data and/or your ability to communicate with the USB-TC.
If the LED turns off
If the LED is lit but then turns off, the computer has lost communication with the USB-TC. To restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore communication, and the LED should turn back on.
Configuring the USB-TC
All hardware configuration options on the USB-TC are programmable with software. Use InstaCal to set the thermocouple type for each channel pair. Configuration options are stored on the USB-TC ’s isolated microcontroller in EEPROM, which is non-volatile memory on the USB-TC module. Configuration options are loaded on power up. The factory default configuration is Type J thermocouple.
Allow the USB-TC to warm up for 30 minutes after powering up before taking measurements. This warm up time minimizes thermal drift and achieves the specified rated accuracy of measurements.
Calibrating the USB-TC：
The USB-TC is fully calibrated via InstaCal. Allow a 30 minute warm up before calibrating.
Sensor Connections
The USB-TC supports type types J, K, R, S, T, N, E, and B thermocouples.
Thermocouple selection
The thermocouple type you select will depend on your application needs. Review the temperature ranges and accuracies of each type to determine which is best suited for your application.
Screw terminal pin out
The USB-TC has four rows of screw terminals ? two rows on the top edge of the housing, and two rows on the bottom edge. Each row has 26 connections. Between each bank of screw terminals are two integrated CJC sensors used for thermocouple measurements. Signals are identified in Figure3-1.
Thermocouple input terminals (C0H/C0L to C7H/C7L)
You can connect up to eight thermocouples to the differential sensor inputs (C0H/C0L to C7H/C7L). The USB-TC supports type types J, K, R, S, T, N, E, and B thermocouples.
Ground terminals (GND)
The six analog ground terminals (GND) provide a common ground for the input channels and DIO bits and are isolated (500 VDC) from the USB GND.

如果您的USB - TC的损坏，立即通知通过电话，传真，或测量计算公司电子邮件。对于国际客户，请联系当地经销商，您购买的USB -训练班。

连接USB -训练班到您的系统，打开你的电脑，并连接USB电缆连接到电脑的USB端口或外部的USB集线器连接到您的计算机。 USB电缆提供电源和通讯的USB -训练班。

当您第一次连接的USB -训练班，一发现新硬件弹出气球（Windows XP）或对话框（其他Windows版本）打开作为USB - TC的检测。

当此气球或对话框关闭，安装已完成。闪光的USB LED应该再继续发光。这表明，通信之间的USB - TC和您的计算机上建立。

注意！不要断开USB总线任何设备，而计算机与通信的USB -训练班，或者您可能会丢失数据和/或你的沟通能力与USB -训练班。
所有的USB - TC的硬件配置与软件编程选项。使用InstaCal设置每个通道对热电偶类型。配置选项都存储在USB -训练班的在EEPROM，这是非易失性的USB - TC的内存模块独立微控制器。配置选项都装上电时。工厂默认配置是J型热电偶。

允许的USB - TC的热身30分钟后供电才采取了测量。这温暖的时间减少热漂移，并达到指定的额定测量精度。

  校准的USB -训练班：

该USB - TC是通过InstaCal完全校准。允许一个30分钟的热身前校准。

传感器的连接

该USB - TC的支持类型类型J，K号，俄，西，睾酮，氮，E和乙热电偶。

热电偶的选择

您选择的热电偶类型将取决于你的应用需求。审查的温度范围和每种类型的精度，以确定哪些是最适合您的应用程序。
螺丝端子引脚输出

该USB - TC的有4个螺丝端子行？两行对房屋的顶部边缘，两行的底部边缘。每行有26个连接。每间银行有两个螺丝端子集成联席会议的热电偶测量的传感器。信号是确定图3 - 1。

热电偶输入端子（C0H/C0L到C7H/C7L）

您最多可连接8个热电偶输入到差分传感器（C0H/C0L到C7H/C7L）。该USB - TC的支持类型类型J，K号，俄，西，睾酮，氮，E和乙热电偶。

接地端子（接地）

这六个模拟地面终端（接地）提供一个输入通道和迪奥位共同点，从USB隔离接地（500伏）。
